As a result, the forest roads in the vicinity or a range of approximately 100 cm from the ground to the damage point incur heavy damage; further, severe damage is caused when the bucking process is conducted outside the cutting area. The damage due to the abovementioned reasons is similar to the damage caused by uphill and downhill yarding. The damage due to line thinning is lesser than that due to point thinning in the inner cutting area, and the damage due to point thinning lower than line outside cutting area. In order to reduce the damages to a high-performance logging system in a narrow space on the forest roads,\nconditions such as the felling direction should be varied, and the characteristics of the\ndistribution of the damage due to bucking should be analyzed further.","subitem_description_type":"Other"}]},"item_41_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"HIRABAYASHI, Eon"}]},{"nameIdentifiers":[{}],"names":[{"name":"SAWAGUCHI, Isao"}]},{"nameIdentifiers":[{}],"names":[{"name":"TATSUKAWA, Shiro"}]}]},"item_41_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"岩手大学農学部附属寒冷フィールドサイエンス教育研究センター"}]},"item_41_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-4339","subitem_source_identifier_type":"ISSN"}]},"item_41_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学農学部農林環境科学科森林科学講座"},{"subitem_text_value":"岩手大学農学部附属寒冷フィールドサイエンス教育研究センター"},{"subitem_text_value":"岩手大学農学部農林環境科学科森林科学講座"}]},"item_41_version_type_27":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"平林, 慧遠"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"澤口, 勇雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"立川, 史郎"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"buif-n39p37-46.pdf","filesize":[{"value":"366.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"buif-n39p37-46.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/8966/files/buif-n39p37-46.pdf"},"version_id":"a052523f-3266-4d9d-a4b6-0f735f5c0345"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"超高密度作業路網を基盤とした高性能林業機械間伐作業による残存木への損傷","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"超高密度作業路網を基盤とした高性能林業機械間伐作業による残存木への損傷"}]},"item_type_id":"41","owner":"3","path":["1506"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-02-15"},"publish_date":"2011-02-15","publish_status":"0","recid":"8966","relation_version_is_last":true,"title":["超高密度作業路網を基盤とした高性能林業機械間伐作業による残存木への損傷"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:20:50.856372+00:00"}
